Regional context, not property-specific evidence. The federal wildfire occurrence database lists 119 fires within 5 miles of Hasan between 1992 and 2020, burning about 454 acres in total. 5 started naturally. 4 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Hainesworth
• La Crosse
• Santa Fe
• Hague
• San Francisco Potano (historical)
• Traxler

Every fire recorded in Alachua County

Regional context, not property-specific evidence. Museums hold 1,767 specimens collected within 10 miles of Hasan between 1860 and 1975: 883 Animalia, 682 Fungi, 132 Plantae, 30 Unrecorded, 24 Protozoa, 16 Chromista. 12 distinct Species records are shown. Collected by A. Gholson Jr., A. Broce, A. H. Smith and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

Regional context, not property-specific evidence. The federal mineral resources record lists 2 workings within 5 miles of Hasan: 1 unknown, 1 prospect. None of them still produces. What was taken out: Sand, Phosphorus-Phosphates, Uranium, Magnesite, Iron, Aluminum, Fluorine-Fluorite. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Every working recorded in Alachua County

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 294799. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
